The work of p
11、reparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental,
12、in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/I
13、EC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility
14、that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

18、ectro-discharge machines (wire EDM).In this International Standard, the tolerances for G1, G2, G3, G4, P1, P2, P3, P4, and P5 have been changed from those in ISO 14137.

19、esting of the accuracy1 ScopeThis International Standard specifies, with reference to ISO 230-1, ISO 230-2, and ISO 230-4, geometric tests, tests of accuracy and repeatability of numerically controlled positioning axes, machining test and circular test for general purpose and normal-accuracy wire el
20、ectro-discharge machines (wire EDM). It also specifies the applicable tolerances, corresponding to the above-mentioned tests.This International Standard is applicable to cross-slide table type machines and double-column type machines.This International Standard deals only with the verification of ac
21、curacy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) nor to the checking of its characteristics (such as speeds, feeds, etc.), which should generally be checked before the testing of the accuracy.This In
22、ternational Standard provides the terminology used for the principal components of the machine and the designation of the axes with reference to ISO 841.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its appli

35、ns and the corresponding tolerances are expressed primarily in ratios, but in some cases microradians or arcseconds may be used for clarification purposes. The following expression should be used for conversion of angular deviations or tolerances:0,010/1 000 = 10 10-6= 10 rad 2” (1)5.2 Reference to
36、ISO 230-1For application of this International Standard, reference shall be made to ISO 230-1, especially for the installation of the machine before testing, warming up of the moving parts, the description of measuring methods and recommended accuracy of testing equipment.In the “Observations” block
37、 of the tests described in Clause 6, Clause 7, Clause 8, and Clause 9, the instructions are preceded by a reference to the corresponding clause/subclause in ISO 230-1, in cases where the test concerned is in compliance with the specifications of ISO 230-1. Tolerances are given for each geometric tes
38、t (see G1 to G8).5.3 Machine levellingPrior to conducting tests on a machine, the machine should be levelled according to the recommendations of the manufacturer/supplier (see ISO 230-1:2012, 6.1.2).5.4 Testing sequenceThe sequence in which the geometric tests are given in no way defines the practic
39、al order of testing. In order to make the mounting of instruments or gauging easier, tests may be performed in any order.5.5 Tests to be performedWhen testing a machine, it is not always necessary or possible to carry out all the tests given in this standard When the tests are required for acceptanc
40、e purposes, the choice of tests relating to the components and/or the properties of the machine of interest is at the discretion of the user, in agreement with the manufacturer/supplier. The tests to be used are to be clearly stated when ordering a machine. A mere reference to this International Sta
41、ndard for the acceptance tests, without specifying the tests to be carried out and without agreement on the relevant expenses, cannot be considered as binding for any contracting parties.Table 2 (continued)4 ISO 2015 All rights reservedBS ISO 14137:2015ISO 14137:2015(E)5.6 Measuring instrumentsThe m
42、easuring instruments indicated in the tests described in the following clauses are examples only. Other instruments measuring the same quantities and having the same or smaller measurement uncertainty may be used. Linear displacement sensors shall have a resolution of 0,001 mm or better.5.7 Diagrams
43、For reasons of simplification, the figures in Clause 6, Clause 7, Clause 8, and Clause 9 of this International Standard illustrate some types of machines.5.8 Software compensationWhen built-in software facilities are available for compensating geometric, positioning contouring and/or thermal deviati
44、ons, their use during these tests shall be based on agreement between the manufacturer/supplier and user, with due consideration to the machine tool intended use.When the software compensation is used, this shall be stated in the test reports.It shall be noted that when software compensation is used
45、, axes shall not be locked for test purposes.5.9 Minimum toleranceWhen the tolerance for a geometric test is established for a measuring length different from that given in this standard, the tolerance may be determined by means of the law of proportionality (see ISO 230-1:2012, 4.1.2). It shall be
46、taken into consideration that the minimum value of tolerance is 0,005 mm.5.10 Positioning tests and reference to ISO 230-2Tests P1 to P5 are applied only to numerically controlled electro-discharge machines.To apply these tests, reference shall be made to ISO 230-2, especially for the environmental
47、conditions, warming up of the machine, measuring methods, evaluation and interpretation of the results.When other numerically controlled axes exist, tests shall be agreed between the user and the manufacturer/supplier.5.11 Machining testConcerning the machining test, only simple machining of a cylin
48、drical hole is proposed. Machining test of other suitable form is also possible under the agreement between the user and the manufacturer/supplier.Machining test shall be made under finishing conditions.The machining test may be substituted by circular test C1.5.12 Circular test and reference to ISO
49、 230-4To apply this test, reference shall be made to ISO 230-4:2005, especially to Clauses 4 and 6 for the test conditions and presentation of results.The circular test may be substituted by machining test M1.
